Illustrate in frame-type structure below in conjunction with Fig. 1～Fig. 6, the concrete correspondence position of non-linear fracture 100 and adhesive tape monomer。For rectangle frame:
One, non-linear fracture 100 as depicted in figs. 1 and 2 be shaped as L-type, it should be noted that adhesive tape is generally of certain thickness, corresponding fracture is to be made up of section (being perpendicular to the adhesive surface of adhesive tape), concrete, informative can be understood as is perpendicular to paper。In the present embodiment, non-linear fracture 100 is made up of the section of the first adhesive tape monomer 11 and the section of the second adhesive tape monomer 12, the section of the first adhesive tape monomer 11 is defined as the first plane, and the section of the second adhesive tape monomer 12 is defined as the L-type structure being made up of the second plane and the 3rd plane, the region that the first plane is positioned at the second plane and the 3rd plane is formed。

Additionally, when non-linear fracture is opened in the corner of adhesive tape 1, light (shown in Fig. 1 the direction of arrow) outwards spills along the horizontal interval in the non-linear fracture 100 of L-type, can be stopped by the second plane in the second adhesive tape monomer 12, and cannot linearly propagate, thus reducing the generation even avoiding leakage problem, and reduce light leak or to avoid light leak be that to be mapped to the angle of incidence of the second plane by light relevant, ideally, when the angle of incidence that light is mapped to the second plane is 0 °, it can be completely returned to, and now can avoid light leak completely。In order to avoid light leak, the distance between side and the 3rd plane of the first adhesive tape monomer 11 can be reduced as far as possible, be mapped to the angle of incidence of the second plane adjusting light so that it is as far as possible close to 0 °。
As in figure 2 it is shown, be shaped as L-type when non-linear fracture, and it is opened on the side of adhesive tape 1。Now the second plane forms the vertical spacing as light outlet with the side, place, long limit of the first adhesive tape monomer 11, and the 3rd plane and the first plane form the horizontal interval as light entrance, horizontal interval and vertical spacing and form the non-linear fracture 100 of L-type。And owing to the first plane is relative with the 3rd plane, first plane is formed along the width of the first adhesive tape monomer 11,3rd plane is formed along the width of the second adhesive tape monomer 12, and therefore, the width of the first adhesive tape monomer 11 is subject to the width restriction of the second adhesive tape monomer 12；In other words, the width of the first adhesive tape monomer 11 and the width of the second adhesive tape monomer 12 are different, when making adhesive tape 1, when cutting the first adhesive tape monomer 11 and the second adhesive tape monomer 12, it is necessary to cutting on the adhesive tape of different in width, add the complexity making adhesive tape 1。
Additionally, when non-linear fracture is opened in the side of adhesive tape 1, light (shown in Fig. 2 the direction of arrow) outwards spills along non-linear fracture 100, can be stopped by the second plane in the second adhesive tape monomer 12, and cannot linearly propagate, even avoid the generation of leakage problem thus reducing, and reduce light leak or to avoid light leak be that to be mapped to the angle of incidence of the second plane by light relevant；Ideally when the angle of incidence that light is mapped to the second plane is 0 °, it can be completely returned to, and now can avoid light leak completely。In order to avoid light leak, the distance of the 3rd plane and the first plane can be reduced as far as possible, be mapped to the angle of incidence of L-type plane adjusting light so that it is as far as possible close to 0 °。
Two, non-linear fracture 100 as shown in Figure 3 and Figure 4 be shaped as Z-type, it is possible to be opened on turning or the side of adhesive tape 1；This non-linear fracture 100 is made up of the section of the first adhesive tape monomer 11 and the section of the second adhesive tape monomer 12, and the section of the first adhesive tape monomer 11 is defined as, the Z-shaped structure that the first plane of being sequentially connected, the second plane, the 3rd plane are constituted；The section of the second adhesive tape monomer 12 be defined as be sequentially connected fourth plane, the 5th plane, the 6th plane constitute Z-shaped structure。
As shown in Figure 3, it is shaped as Z-type when non-linear fracture 100, and it is opened in the state at the turning of adhesive tape 1, now the first plane and fourth plane form the first vertical spacing as light outlet, second plane and the 5th plane form the first horizontal interval, 3rd plane and the 6th plane form the second vertical spacing, and the first vertical spacing, the first horizontal interval and the second vertical spacing are sequentially communicated into the non-linear fracture of Z-type。
When non-linear fracture 100 is opened in the side edge of adhesive tape 1, light (shown in Fig. 3 the direction of arrow) outwards spills along non-linear fracture 100, can be stopped by the 6th plane in the second adhesive tape monomer 12, and cannot linearly propagate, even avoid the generation of leakage problem thus reducing, and reduce light leak or to avoid light leak be that to be mapped to the angle of incidence of the 6th plane by light relevant；Ideally when the angle of incidence that light is mapped to the 6th plane is 0 °, it can be completely returned to, and now can avoid light leak completely。And the angle of incidence being mapped to the 6th plane in order to adjust light is 0 °, it is possible to connect the 7th plane again in the 6th plane, the side, place, long limit of the 7th plane and the first adhesive tape monomer 11 forms the second horizontal interval as light entrance；Then adjust the distance between the 7th plane and the long limit of the first adhesive tape monomer, to adjust the width of this horizontal interval, light can be adjusted whereby and be mapped to the angle of incidence of the 6th plane, make light be mapped to the angle of incidence of the 6th plane as far as possible close to 0 °, to reduce light leak。
As shown in Figure 4, it is shaped as Z-type when non-linear fracture 100, and when being opened in the side of adhesive tape 1, now the first plane and fourth plane form the first horizontal interval as light outlet, second plane forms vertical spacing with the 5th plane, 3rd plane and the 6th plane form the second horizontal interval as light entrance, and the first horizontal interval, vertical spacing, the second horizontal interval are sequentially communicated the non-linear fracture forming Z-type。
When non-linear fracture 100 is opened in the side of adhesive tape 1, light (shown in Fig. 4 the direction of arrow) outwards spills along non-linear fracture 100, can be stopped by the 6th plane in the second adhesive tape monomer 12, and cannot linearly propagate, even avoid the generation of leakage problem thus reducing, and reduce light leak or to avoid light leak be that to be mapped to the angle of incidence of the 5th plane by light relevant；Ideally when the angle of incidence that light is mapped to the 5th plane is 0 °, it can be completely returned to, and now can avoid light leak completely。In order to avoid light leak, the distance of the 6th plane and the 3rd plane can be reduced, to reduce the width of the second horizontal interval, thus adjusting light to be mapped to the angle of incidence of the 6th plane so that it is as far as possible close to 0 ° as far as possible。
By above-mentioned analysis it can be seen that when non-linear fracture is opened in the corner of adhesive tape 1, the section structure of the second adhesive tape monomer 12 is more complicated, therefore, it can the width setting the second adhesive tape monomer width more than the first adhesive tape monomer。
